GF82.85-P-3114-08TA Operating, Display Unit With Control Unit, Function
- with CODE (527) Navigation module for COMAND


The COMAND operating, display and control unit (A40/3) contains a graphics/and video-capable 6.5"-color display for presenting the relevant information as well as the function keys for operating the system. Part of the controls are assigned with permanent functions, i.e. they always trigger the same reaction irrespective of the screen applied in each case. The functionality of the remaining controls depends on the current screen. The components integrated into the system are connected via the MOST ring. As a result the components do not need any individual controls.
It should be observed that the data and signals are transmitted via MOST ring and via the audio gateway control unit (N93/1).
The COMAND operating, display and control unit (A40/3) is equipped with an integral multistandard disk drive for Video-DVD, Audio-CD, MP3-CD-ROM disk drive.

Graphic editing and image output
The operating masks are internally output to the display by the graphics subsystem via the RGB output (R=red, G=green, B=blue). The information and amplitudes of the three colors red, green and blue as well as a synchronization signal are included in the RGB signal.
The electronic circuitry in the display unit evaluates the RGB signal and actuates the individual display pixels line by line in terms of color and intensity.A horizontal synchronization pulse occurs at the end of each line. The electronic circuitry of the display unit then starts the next line.

Display
On the 6.5" color display of the COMAND operating, display and control unit (A40/3), the submenus are displayed depending on the choice of the permanently programmed main function keys (function groups). 5 function key are positioned on the left and right edge of the display. The buttons are positioned so that the displayed submenus can be selected comfortably.

Off-board diagnosis, STAR DIAGNOSIS
The COMAND operating, display and control unit (A40/3) has its own diagnostic trouble code memory.
When the diagnostic trouble code memory is called up by means of STAR DIAGNOSIS, the data are transmitted to the audio gateway control unit (N93/1) via the MOST ring and can then be read out via the central gateway control unit (N93) interface. Output of the errors on the display unit is not possible.
